property ToolBar.Background(Part as BackgroundPartEnum) as Color
Returns or sets a value that indicates the background color for parts in the control.

TypeDescription
Part as BackgroundPartEnum A BackgroundPartEnum expression that indicates the part to be changed
Color A Color expression that indicates the background color for a specified part. The last 7 bits in the high significant byte of the color to indicates the identifier of the skin being used. Use the Add method to add new skins to the control. If you need to remove the skin appearance from a part of the control you need to reset the last 7 bits in the high significant byte of the color being applied to the background's part.
Use the Background property to specify a different visual appearance for parts of the control, such as tooltip, check or radio buttons.

The following screen shot shows the check-boxes, as they are shown by default:

The following screen shot shows the check-boxes, as once a new visual appearance is applied:

How can I change the visual appearance of the check-boxes to be displayed in the toolbar control (ebn)?
